HAYSTACKER.

Application filed September 28, 1925.

This invention relates to hay stackers, one of its objects being to provide cooperating means whereby, during the operation of the stacker the head of the stacker will be moved upwardly relative to its supporting means and thence moved downwardly to its normal position, the entire operation being etlected solely bypulling and thereafter releasing the operating cable.

A further object is to provide a stacker requiring less power to elevate the load a given distance than has been heretofore reouired, this being due to the fact that the distance ot the stacker head from its tulcruni gradually increases the head is moved upwardly.

inother object is to provide a hay stacker which is very compact in construction and which. when in normal position occupies space than other stacker-s capable of claw ing to the same height.

A further object- .is to prov'de adjustable means for varying the height t which the head oi the stacker will convey a load.

Another object is to provide simple and etliciont means tor reinforcing the working parts oi the stacker so as to prevent them :troni swaying laterally while in operation.

i lnother object is to provide a hay stacker having a novel form of truck readily movable into and out of operative position and by the use of which the stacker can be moved easily from place to place.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, .it being understood that changes in the precise embodiment ot the invention herein disclosed may be made within the scope of what is claimed with out departing from the spirit of the invention.

In the accompanying drawings the preferred torm of the invention has been shown.

In said drawings,

Serial No. 58,116.

(S are pivotally connected'to the sills 1 close to the beam and carry an axle 7 engaged by wheels 8. These arms with the connecting axle and the wheels form a truck and when it is not desired to .use the truck for supporting one end of the mechanism the arms 6 can be extended upwardly as shown in Figures 2 and 3. W hen it is desired to use the truck. however, said arms are swung dmvnwardly so as to bring the wheels against the ground. these parts being held so positioned by the weight of the stacker head resting on the arms as hereinafter explained.

Extending upwardly from and secured to the side sills 1 adjacent those ends thereof remote from the truck, are standards 9 connected, near their upper ends, by a cross beam 10. Another standard 11 is mounted on the middle portion of the crossbeam 2 and is fastened to the middle portion of the upper cross beam 10 and secured to the sides of the upper end portion of this standard 1]. are parellel inclined beams 12 the lower ends of which are securely fastened to the middle portion or? the cross beam l while the upper end portions thrust upon and BX- tend upwardly beyond. the beam 10 to which they are attached. Downwardly diverging braces 13 are attached to the upper ends of these beams 12 and extend downwardly and are attached to the end portions of the beam 2. Thus the upstanding frame provided at one end of the machine is braced against lateral sagging. A pulley id is journaled between the upper end portions of their.- clined beams 12 and another pulley 15 journaled between brackets 16 secured to said beams and to the upper end of the standard 11. See Figure 6. Inclined side braces 17 connect the upper end portions of the standards 9 to the side sills 1.

Pivotally connected to the upper ends of iii) the standards 9 are lifting beams 18 each of which is provided with a longitudinal slot 19. Reinforcing blocks 20 are attached to the upper end portions of standards 9 and serve to strengthen the structure at these points where considerable strain is received. Pins 21 are removably mounted in the bean'is 18 adjacent the pivot ends thereof and are adapted to extend across the adjacent ends of the slots 18. Each pin can be inserted into either of two spaced openings 22 in the beam.

Pivotally connected to the ends of the cross beam 4 are lifting bars 23 the free end portions of which are connected by cross strips 24 suitably braced as shown at 25. hen the stacker is not in use one of these cross strips 24- can rest upon the arms 6 as shown in Figure 4 so as to force the wheels 8 downwardly below the ends of the sills 1. A pitman 26 is pivotally connected to each of the lifting arms 23 close to its pivot 27 and each of these pitmen is fiivotally connected, at its upper end, to one of the slotted beams 18, as shown at 28.

Converging lifting beams 29 are pivotally mounted upon a cross rod 30 or the like car-- ried by the sills 1 and carry a pulley 31 be tween their upper ends. Braces 32 are attached to these converging beams adjacent the sides of the pulley 81 and are pivotally connected to the lifting arms 23 at Guide sleeves 34 are attached to the lifting arms 23 close to the free ends thereof and are engaged by sliding arms 35 mounted on the lifting arms. These sliding arms also carry sleeves 36 which slidably engage and extend partly or entirely around the lifting arms 23. The sliding arms are provided, at their outer or upper ends with cross beams 37 to which are connected the tines 3S and 39 of the stacker head 40. These tines 38 and 39 are disposed at obtuse angles in the preferred construction sothat, during the operation of lifting a load the tines 39 will Support the same whereas, during the completion of the lifting operation and during the delivery of the load said load will be supported by the tines 38. This construction is a well known one and it is not deemed necessary to enter into a detailed description or to illustrate the same specifically. An elon gated roller 40 in the form of a pipe or the like is mountedto travel within the slots 19 in beams 18 so that said beams thus constitute a track. The ends of this roller are in engagement with pitmen 41 pivotally connected to the sliding arms by removable pins 42. These pins can be placed in any one of a series of apertures 43 formed in each of the sliding arms 35.

One end of a hoisting cable 44 is attached to a yoke 45 in which the pulley 31 is mounted to rotate. From this yoke the said cable is extended over the pulley 15 and under the same back to and under the pulley 31. is then extended over said pulley 31 a; back over the pulley 14. Thence the cable is extended downwardly under a pulley 4-5 connected to the cross beam 2 adjacent the center thereof. The free end of the cable can be attached to any suitable means whereby the same can be drawn longitudinally for the purpose of operating the stacker. In order to prevent the stacker from tilting under the strain resulting from this pull the extension arms 46 can be connected to and projected beyond the ends ot the sills 1, these arms being reinforced by braces 47.

The upward swinging movement of the stacker head is cushioned by a compression spring 48 mounted between the center of the cross beams 3 and a cable 49 is attached to the center of one of the beams 37 of the stacker head.

Under normal conditions the .sliding arms 35 rest upon the lifting arms 23. so that the weight of the stacker head and the parts carit id ried thereby is transferred to the arms 6 and the wheels 8 are caused to project below the sills 1 as shown in Figure 4 and as hereto-- fore explained. lVith the parts thus located the beams 29 are inclined as shown in Fig.1- ure 2 with the stacker head projecting outwardly beyond the ends of the sills. A team or a tractor can be hitched to the other end of the structure and said structure readily transported from place to place.

lVhen the machine has been brought to the place where the material is to be stacked, the lifting arms are swung upwardly so as to allow the arms 6 to be swung upwardly to the positions shown in Figures 2 and 3. Thus the sills 1 will rest firmly on the ground. At this time the roller or pipe .0 is located in those portions of the slots 1?) remote from the standards 9. The material. to be stacked is placed upon the tines f") and after the pins 42 have been placed in the openings 3 nearest the stacker head the cable 44 is pulled to operate the stacker. The pulling of this cable causes the beams 29 to swing upwardly about their pivot lit) and. by reason of the connections 32 between these beams and the lifting arms 23 said arms 23 will also swing upwardly about their pivots 27. As the sliding arms are supported on the arms 23 they, too, will be swung upwardly. carrying the stacker head with them. During this upward swinging of the parts the roller 40 will travel along the slots 19 and toward the pins 21. As long as the movement of the roller within the slots is not obstructed the sliding arms 35 will not change their positions relative to the lifting arms 23. By the time the roller 40 comes against the pins 21 the weight of the load has been transferred from the tines 39 to the tines 38. Further pulling of the cable ll will cause the beams 29 to continue to swing towards the cross beam 10 but as the pitmen ll cannot travel any further within the slots 19 they will exert a thrust against the sliding arms 35 with the result that, during the further upwarc. swinging movement of the stac for head, the arms will be shifted longitudinally along the lifting arms 23 and the load arried by the stacker head will be pushed almost straight uliwardly to the predetermined level. lVhen the stacker head is brought to the upper limit of its movement the tines 38 will be slightly inclined so that the load will gravitate therefrom onto the stack. After the load has thus been elevated the cable is paid out to permit the stacker head to return to its normal or lowern'iost position. During the first portion of this return movement the sliding arms 35 will. gravitate downwardly along the lifting arms 28 after which the pitmen ll will draw the pipe or roller 40 along the slots 19 to its forwarifl position therein. After the stack has been built up to a certain height making itnecessary to elevate the load to a higl'ier level, the pins l2 are withdrawn from the apertures nearest the head 40 and the pitmen ll are adjusted back so as to allow the pins to be inserted into the next adjoining apertures d3. Thus during the next lifting operation of the stacker the head 4E0 will be raised to a still higher elevation. Thereafter pins 1-2 can be placed in the remaining apertures l3 successively until the limit of elevation by the stacker has been reached. ()bviously the closer the pins as are placed to the pivots of the lifting arms 23 the more extensive will be the sliding movement of the arms 35 upon the lifting arms 23 and, consequently, the hi her will be the lift of the load. Importance is attached to the fact that, by the use of the tracks formed by the slotted beams 18 together with the pitmen el-l and the cooperating lifting arms and sliding arms 23 and 2-35 respectively the power required to elevate a load to a relatively high point is much less than has heretofore been necessary because the upward l'l'lOVGll'lOlll] of the load relative to the lifting arms begins after said arms have been elevated to points where the hoisting cable is relieved of much of the lifting strain.
